Changes:
- Ensure proper shutdown in non-interactive mode
- Ensures the initial user prompt is logged in non-interactive mode
- Improve telemetry for streaming - handle chunks and input token count is now alongside other token counts in response
To test:
- Follow instructions in https://github.com/google-gemini/gemini-cli/blob/main/docs/core/telemetry.md#google-cloud
- Run CLI in non-interactive mode and observe logs/metrics in GCP Logs Explorer and Metrics Explorer
#750
Refactor OpenTelemetry logging for API requests, responses, and errors. Moved logging responsibility from GeminiClient to GeminiChat for more detailed logging.
#750
Add the user's decision (accept, reject, modify) to tool call telemetry to better understand user intent. The decision provides crucial context to the `success` metric, as a user can reject a call that would have succeeded or accept one that fails.
Also prettify the arguments json.
Example:

#750
Adds the following attributes to the event:
- embedding_model
- api_key_enabled
- code_assist_enabled
- debug_mode
- mcp_servers
This additional data will provide more insight into user configurations.
Adds the text content of the API response to the telemetry event. This provides more context for debugging and analysis without logging the entire, potentially large, response object.
- Adds an optional field to the type.
- Updates to include the field in the logged attributes.
- Modifies the to extract the response text using and pass it to the logger.
- Adds a new test file for the telemetry loggers, including tests for the function to verify the new functionality.
